Unused sheet of thirty-six souvenir “Atomic Bombs End World War II” stamps (not official postal stamps), 11 x 8.5, signed in blue felt tip in the lower margin, “Paul Tibbets, Pilot, Enola Gay.” The U. S. government cancelled plans for a similar official postage stamp because of controversy surrounding the “celebration” of the atomic bomb. In very fine condition. R&R COA.
